A lot. When I buy ammo, I normally get a case of 9mm valuepacks (1000/case), two cases of .45 valuepacks (500/case), a buncha 12 gauge slugs (normally all five boxes on the shelf), and a buncha .22, even if I have plenty. All at walmart, where I can also get a case of motor oil, do grocery shopping, and buy more socks.
Havent got an ammo in a while, gonna have to go again soon.
